The supermodel, who is married to actor Orlando Bloom, will strut her stuff at next month's (Nov11) event in the aqua-coloured Fantasy Treasure Bra, partly created by Long Island's London Jewelers - and she can't believe she will be wearing more than 142 carats of white and yellow sparklers on her chest alone.
Kerr tells People.com, ""It's such an honour to wear the bra. And it's such a piece of artwork! It's absolutely stunning - it kind of feels a little mermaid-like - but I can't believe I'm wearing $2.5 million on my chest.""
The lingerie presentation will mark Kerr's return to the catwalk for the lingerie and underwear brand since giving birth to her son Flynn earlier this year (11).
